Before measuring closely inspect the firebox and look for anything that will hinder the operation of the glass and track system. Things to look for are: protruding screw heads, existing tracks that may have to be removed, damper handles, shields, or venting.
Proceed by measuring the width of the firebox Y/Z. Next measure the height of the firebox A/B/C. Transpose the smallest width x smallest height into the order form.

Also care must be taken when measuring to insure that the firebox will accept the track assembly shown below. Firebox must be reasonable square for Glass & Track Doors to operate properly. For out of square conditions choose the custom full fold bifold model!

NOTE: Make sure that your measurements are correct. Custom doors are not returnable.
CUSTOM GLASS & TRACK
This type of door will only work if the old track on your firebox can be removed. When track can not be removed you have to order the full fold bi-fold door.

Door fits inside the firebox opening and made with air gaps to allow necessary air ventilation for factory-built fireplaces. These doors are custom made to fit your size measurements you supplied. It is the buyers/purchasers responsibility to verify that the door will fit in accordance to above mentioned guidelines.
Door is custom made to your size and can not be returned.
